Description

The invention relates to a device for spraying a liquid and can be used in any field of national economy, where necessary, humidifying the air, spraying toxic chemicals and other liquids.

A device for obtaining highly dispersed aerosols, containing associated connecting tube. θ tanks for the sprayed liquid, equipped with nozzles coaxially arranged one against the other with concentrically mounted nozzles and inlet nozzles for supplying compressed air to the nozzles [Ϊ]. 15

The disadvantage of this device is its low productivity, since periodically the liquid being sprayed is periodically manually poured into the tanks and the device is turned off at this time. This time-consuming operation takes a lot of time, which significantly lengthens the interval between two working cycles — 25 minutes.

com and main water supply network with a shut-off valve at the end [U].

The shortcoming of this device is low productivity when it is used to humidify the air in rooms with a large area, since the aerosol generators are filled with water from the tank by gravity, i.e. the filling rate of aerosol generators in a known device is directly dependent on the height of the water column in the tank. To increase the height of the water column in the supply tank and thereby increase the water pressure in the proposed device is impossible, since the supply tank is also a regulator of the filling level of aerosol generators.

The purpose of the invention is to improve the performance of the device by accelerating the process of filling aerosol generators.

To achieve this goal, in a device for spraying a liquid containing aerosol generators connected to a tank with a supply pipe with a float and a supply network with a shut-off valve, supply water 3

The conduit pipe is connected to the shut-off valve of the water mains supply line, the device is equipped with control valves installed at the inlet of the aerosol generators and the tank along the flow path of the fluid. The tank is equipped with a magnet fixed to the float and a contact interacting with it, installed at the top of the tank and electrically connected to the shut-off valve.

This embodiment of the device for spraying a liquid allows you to fill the aerosol generators under the pressure of the water mains of the water supply network, which significantly reduces the time of their filling compared with the known device.

The drawing shows a diagram of the device.

A device for spraying a liquid contains aerosol generators 1, a tank 3 connected to them by a feed tank 2, a tank 3 with a float 4, and a main water supply network 5 with a shut-off valve 6. A supply pipe 2 is connected to a shut-off valve 6 of a water supply network 5. '

The device is equipped with control valves 7 installed at the entrance of the aerosol generators 1 and the tank 3 in the course of the feed material.

The tank 3 is provided with a magnet 8 fixed on the float 4 and a contact 9 interacting with it, installed in the upper part of the tank 3 and electrically connected to the shut-off valve 6 through the actuator 10.

Aerosol generators 1 contain nozzles 11 installed one against the other with concentrically positioned nozzles 12 and inlet nipples 13 for supplying compressed air to the nozzles 11. Aerosol generators 1 are interconnected by tubes 14, on which check valves 15 are mounted.

The device works as follows.

Water from the mains supply network 5 through the shut-off valve into the feed pipe 2 and through the adjusting valves 7 fills the aerosol generators 1 and the tank 3. Since the tank 3 is connected to the aerosol generators 1 through the feed pipe 2, the water level in the tank 3 and aerosol generators 1 is set the same. When a specified water level is reached in aerosol generators 1, the float 4, supplied with a magnet 8, floats and μιγηητομ 8 interacts with pins 9, closing the electrical circuit of the actuator 10, which closes the stop valve 6, interrupting the water supply to the water supply network 5 to the feed pipe '2. I ri feed

compressed air to the nozzles 11 through the inlet nozzles 13 in aerosol generators 1 and connecting tubes 14 creates an increased pressure, which causes the check valves 15 to close, which prevents the return water from the generators to the feed pipe 2. The resulting mixture of highly dispersed aerosol from the nozzles 11 is sent to the nozzles 12 and sprayed. At the termination of the air supply in aerosol generators one after complete or partial exhaustion of their water return valve 15 opens, the float 4 provided with (a magnet 8, is omitted, the electric _(kai chain actuator 10 is opened and the shut-off valve 6 is opened. This ensures free access of water from the mains network 5 to aerosol generators 1. In the future, the cycle of operation of the device for spraying a liquid is repeated.

The presence of control valves in the device, the diameters of which are set inversely proportional to the removal of aerosol generators from the mains water mains, allows filling all aerosol generators simultaneously, regardless of their distance from the mains water mains, as the decrease in water pressure by the end of the supply pipe is compensated by increasing the diameters of the regulating valves proportionally drop this pressure. Filling the tanks of aerosol generators under pressure equal to the pressure of water in the mains water mains, significantly reduces the time to prepare the device for operation and thereby improves its performance in comparison with the known.

The proposed device provides a high-performance liquid spraying process.
